    input power equals output power plus power losses of the adaptor. minimal lang naman ang losses ng adpator so negligible so puede mo ng computin ang watts used by the laptop sa output ng adaptor..

    Ingat kayo sa pagbili ng mga inverters na yan. Dati bumili kami sa DIY Gateway, binalik ko lang. Its actual output was in excess of 500 volts, so siguradong tostado mga isasaksak ko dun. We brought a voltmeter when we returned it para makita nila talaga. They offered to replace it, kaso lahat ganun. Sorry, I forgot what brand it was, but its form factor is similar to the pic above.

    your idea is indeed very logical. Ang normal household appliance is barely less than 100watts lang nga.

    ang pinagtataka ko lang kasi I have 2 inverters - both are rated 300watts. My older unit got busted but a close friend of mine managed to repair it. After that repair working siya sa Toshiba Libretto charger ko. Then when I shifted to a Neo Laptop charger hindi na nito kinaya. Lagi itong nag - "ooverload". Pero sa cellphone charger walang problem ito.

    Napilitan tuloy akong bumili sa Alexan ng 300watt inverter nila. This one worked very well with the Neo charger.

    So I deduced that I would need a 300watt inverter for laptops and nothing less.

    Pero kung gagana yung cute na inverter na pinost ni Boybi sa laptop niya, i would want to buy one too.

    Boybi, pagnatuloy kang bumili, tell us your opinion on that.

    Baka BLADE yung shop na nakita mo. Yung higher wattage nila is around P1600 I believe, and its only 175 watts max output.

    Ah yes, that's the one - Blade

    Di ko pa nakita yung sa CD-R King.

    Sa Raon, the cheapest 300w one I found was P2000, natawaran ko ng P1900... mukha din siyang amp...

    Mura CDR-King. Less than 1000 price. Oks sya at eto gamit ko ngaun, nakakayanan namang icharge ung laptop ko and so far oks ang takbo. Dalawang saksakan pa pwede saksakan (pero normally pag parehong phone chargers lang, kasi pag laptop ung isa sabay laptop din ung isa pa, alanganin, 150watts lang kasi).
